A Review | Constants Periodic Table Part B Learning Goal: To learn how to calculate the binding energy of a nucleus. The actual measured mass of a fluorine-19 atom is 18.998403 amu . What is the mass defect, Am, for a fluorine-19 nucleus? Express your answer in atomic mass units using six significant figures. The measured masses of nuclei are consistently lower than predicted by the sum of their particles. This discrepancy is called the mass defect, and it can...

Stars generate energy through nuclear fusion. A fusion reaction is exoergic (i.e., it gives off energy) if the product has a lower rest energy than the original nuclei. The binding energy of a nucleus is defined as the difference between the rest energy that the individual particles would have if they were not bound in a nucleus and the rest energy of the nucleus itself. So, stated another way, fusion reactions are exoergic if the binding energy of the product...

Review | Constants | Periodic Table
Chemists often use molarity MM, in moles/litermoles/liter, to
measure the concentration of solutions. Molarity is a common unit
of concentration because the volume of a liquid is very easy to
measure. However, the drawback of using molarity is that volume is
a temperature-dependent quantity. As temperature changes, density
changes, which affects volume. Volume markings for most laboratory
glassware are calibrated for room...
